DANGEROUS

                   DANGEROUS
the power input hall be input after the terminal cover is well installed. please do not destach the cover when the power is on.
if the inverter's power-failure restart function is enable'and electr-
omagnetic contactor is not installed at the input side'please keep
away from the equipment'because the inverter will be started
suddenly when the power is vailable.

                      NOTE
when braking device is installed'the high voltage discharge at the two ends of the braking resistor.it could cause electric shock or
burns.please check again the rating of the motor and other machine
before operation.it could lead to human injury.please do not check
the single during operation. it could lead to the equipment's damage.please change the inverter's setting as you wish'this series
of inverter has been set properly before shipment.it could damage
the carrier frequency needs to be set again whenever the operation of factory default reset is executed'otherwise' the inverter could be damaged.the inverter with different capacity shall be set with different carrier frequency.please find the description in c6-01-03 of 4.2.it could
lead to the damage of the inverter.  

AC 3PHASE INVERTER,S WIRING NOTES

          WIRING NOTES

1 . when dismounting the'motor please cut off the power supply
     first.
2 . the switch over of motor or mains supply can be done only
     when inverter's output stops .
3 . when the inverter is installed with exterior devices  (barking
     unit' reactor'filter) please test the devices'resistance to the
     ground by 1000v level megameter and make sure the
     resistance is not less then 4m.
4   input command single cable and frequency meter cable need
     to be shielded'and it also should be wired separatedly.it is
     better to kept away from the main circuit connection.
5   to avoid from the wrong action caused by interference'the
     control circuiting cable shield be twisted pair cable'and the
     wiring distance shall be less the 50m.
6   please do not make shielding cable connect to the single
     cable or machine's housing.the naked wire shall be wraped by
     isolation tape.
7   all the lead wires  voltage with stand level shall be same as the inverter's voltage level.
8   to avoid of accident'control grounding terminal g must be well connected to the ground.the grounding wire      cann't be the other equipment's grounding wire.the grounding wire specification shall be bigger then half of
     the above-said wire specification.when the wiring is completed'please check whether there is cable'screw
     or connector lug left in the equipment or not'whether the screw is loose 'whether the naked wire of the
     terminal is short-circuited to the other terminal.  




     

AC 3PHASE INVERTER,S CONTROL CIRCUIT TERMINAL WIRING DESCRIPTION

CONTROL CIRCUIT TERMINAL WIRING DESCRIPTION.

to reduce the control signal's interference and attenuation' the control signal's wiring length shell be limited within 50 cm and the distance to the power cord shell be longer than 30 cm. when connecting the along input and output signal' please use twisted pair cable and connect one end of the shielding sleeve to the ground.

CONTROL CIRCUIT CONNECTION NOTES.

to layout separatedly the control circuit cable'main circuit cable and other power supply cable. to avoid from
the wrong operation cased by interference' control circuit cable needs to be twisted pair cable. the connection distance shall be less than 50 m. the distance to power cable needs to be more than 30 cm. please use twisted pair cable for the command from terminal. please see below when the output contact of multifunction  optical coupler connects to relay' coil's two ends needs to connect to bypass diode in parallel.
please do not make shielding cable connect to the single cable or machine's housing. the naked wire shall be
wraped by isolation tape.
contact output terminal 9'10'18'19'20' must be connected to terminal 1~8'11~17'21~23'25~27'33 independently.  



    

AC 3PHASE INVERTER,S CONDUCTION INTERFERENCE PREVENTION METHOD.

CONDUCTION INTERFERENCE PREVENTION METHOD.

to suppress the conduction interference from the output side' it is applicable to let all the input cables go through a grounded metal tube.







THE WIRING DISTANCE BETWEEN INVERTER AND MOTOR.

the longer the wiring distance between the inverterand motor is' the higher there carrier frequency is and the  gigger the upper harmonics current in the cable is . the current leakage will implement bad effect on the embient equipment . in this case it is necessary to minimize the current leakage. please find below table for the relation between the wiring distance (between the inverter and motor ) and carrier frequency .

AC 3PHASE INVERTER,S PHASE-SHIFT CAPACITOR IS NOT ALLOWED TO USE.OF INVERTER.

please do not connect phase-shift capacitor or lc/rc filter to the output circuit. otherwise'the inverter will
be burned.






ELECTROMAGNETIC SWITCH BETWEEN INVERTER AND MOTOR IS ALLOWED TO USE.
please do not connect electromagnetic switch'electromagnetic contactor to the output circuit.otherwise'
the inverter's surging current will lead to the action of over current protection. in serious case'the inverter's
internal parts could be damaged.

please install a mccb which is compatible to the inverter' capacity .

1  . the capacity of mccb should be 1.5-2 multiples of the inverter's rated current . mccb's time characterics
shall satisfy the inverter's overload protection characteristics (150% of the rated current /minute' 180% of the rated current/2 second )

2  . when mccb is shared by two or above motors or other equipment ' please connect according to the below fig . connect the fault output relay contact of the inverter to the power supply contactor and cut off the
input power supply .

THE INSTALLATION AND SELECTION OF ELECTROMAGNETIC CONTACTOR.
to cut the main circuit power supply at the fault of inveryer and prevent the inverter from restarting at fault' please install electromagnetic contactor on the power supply side of the inverter.

RFI PREVETION  SOLUTION.
input cable'output cable and the inverter itself all can create fri. dedicated filter needs to be used at both input
side and output side of the inverter. the normal filter cann't achieve the expected effected. and the input and output terminal shell be custom-made. the rfi can be reduced to use iron device for shielding the connecting
cable between inverter and motor shall be as short as possible. please find below for the rfi prevention.
